Cookies do not work on localhost in tear
 

I installed tear 0.31 with libwebkit and use local web pages with cookies which do not work on tear. It seems cookies are disabled in local webpages.
I tried file://..... URL but als http://localhost/... (I have the lighttpd web server running on the N810).
I am sure it is not a problem of lighttpd as other browsers (including MicroB) support local cookies normally.
What is the problem here ?
